1987 Honda Accord LX in AZ

The 3rd cylinder has a loud knock - probably a rod bearing. It still runs and is otherwise intact, but it lacks power. The head has under 50,000 miles on it( we have all receipts). It is auto, carbureted, 4dr, dk gray and the body is straight with no rust. We are located in Mesa AZ. Make reasonable offer (480) 503-2937.
